add basic interface alias support. for now (since we don't use ip in our network scripts yet), it adds :1, :2, ... alias interfaces this will change when we add support for the ip utility, but the config format will remain the same. example:
config alias test option interface lan option ipaddr 192.168.1.1 option netmask 255.255.0.0 SVN-Revision: 12241
